Help with nodemcu esp8266 and neo 6m

Hello everyone, i have a graduate project and i have come to a dead end.
so the project is a 4wd car with 4 motors, l298, an ultrasonic sensor, ir line sensors, arduino uno, a nodemcu esp8266 dev board and a neo 6m gps module.In the end you will tell it to come to you over network and with the gps will be guided there avoiding the obstacles
We have tested everything separately, and even controlled the vehicle through wifi.
What we cant figure out is how can i send somewhere over wifi or a network(website etc) the data from neo 6m, or the opposite, from a smartphone for example its coordinates to the arduino. In a few words how to connect esp8266 and gps on the arduino to work together
